"He is, however, the only player in our first-team squad that has such a contract clause."

The clause is thought to be in the £30 million mark, which could entice either Arsene Wenger or David Moyes into a January bid. But who needs him more?

Arsenal have a decidedly German influence on their squad, with superstar Mesut Ozil the big-name summer signing.

The former Real Madrid man joins the likes of Per Mertesacker, Serge Gnabry and Lukas Podolski in the Gunners’ contingent, with the north Londoners being linked with moves from more German players.

However, given the presence of Ozil and Santi Cazorla, and with Theo Walcott and Alex Oxlade-Chamberlain to return to the fold from injury, Wenger has a plethora of attacking midfielders to pick from.

Reus would certainly be an excellent addition, but the French boss has other areas that take priority in the transfer market.

United on the other hand could really use Reus, as there are major question marks over the Premier League champions’ widemen and a lack of creativity in the side. The German attacker could well fix both issues by moving to Old Trafford.

With Nani, Ashley Young, Shinji Kagawa and Antonio Valencia inconsistent and Adnan Januzaj inexperienced, Reus would be the hit of quality and ability that would make Moyes’ men a more dangerous outfit.

With a lack of creativity centrally, Reus could be the answer as he tends to cut off his wing, moving inside with and without the ball for Dortmund.
